S29GL064S
General Description
The S29GL-S mid density family of devices are 3.0-volt single-power flash memory manufactured using 65 nm MirrorBit technology.
The S29GL064S is a 64-Mb device organized as 4,194,304 words or 8,388,608 bytes. Depending on the model number, the devices
have 16-bit wide data bus only, or a 16-bit wide data bus that can also function as an 8-bit wide data bus by using the BYTE# input.
The devices can be programmed either in the host system or in standard EPROM programmers.
Access times as fast as 70 ns are available. Note that each access time has a specific operating voltage range (V
CC
) as specified in
the
Product Selector Guide
and
Ordering Information.
Package offerings include 48-pin TSOP, 56-pin TSOP, 48-ball fine-pitch BGA,
and 64-ball Fortified BGA, depending on model number. Each device has separate chip enable (CE#), write enable (WE#) and
output enable (OE#) controls.
Each device requires only a
single 3.0-volt power supply
for both read and write functions. In addition to a V
CC
input, a high-
voltage
accelerated program (ACC)
feature is supported through increased voltage on the WP#/ACC or ACC input. This feature is
intended to facilitate system production.
The device is entirely command set compatible with the
JEDEC single-power-supply flash standard.
Commands are written to
the device using standard microprocessor write timing. Write cycles also internally latch addresses and data needed for the
programming and erase operations.
The
sector erase architecture
allows memory sectors to be erased and reprogrammed without affecting the data contents of other
sectors. The device is fully erased when shipped from the factory.
The
Advanced Sector Protection
features several levels of sector protection, which can disable both the program and erase
operations in certain sectors. Persistent Sector Protection is a method that replaces the previous 12-volt controlled protection
method. Password Sector Protection is a highly sophisticated protection method that requires a password before changes to certain
sectors are permitted.
Device programming and erasure are initiated through command sequences. Once a program or erase operation begins, the host
system need only poll the DQ7 (Data# Polling) or DQ6 (toggle)
status bits
or monitor the
Ready/Busy# (RY/BY#)
output to
determine whether the operation is complete. To facilitate programming, an
Unlock Bypass
mode reduces command sequence
overhead by requiring only two write cycles to program data instead of four.
Hardware data protection
measures include a low V
CC
detector that automatically inhibits write operations during power
transitions. The hardware sector protection feature disables both program and erase operations in any combination of sectors of
memory. This can be achieved in-system or via programming equipment.
The
Erase Suspend / Erase Resume
feature allows the host system to pause an erase operation in a given sector to read or
program any other sector and then complete the erase operation. The
Program Suspend / Program Resume
feature enables the
host system to pause a program operation in a given sector to read any other sector and then complete the program operation.
The
hardware RESET# pin
terminates any operation in progress and resets the device, after which it is then ready for a new
operation. The RESET# pin may be tied to the system reset circuitry. A system reset would thus also reset the device, enabling the
host system to read boot-up firmware from the flash memory device.
The device reduces power consumption in the
standby mode
when it detects specific voltage levels on CE# and RESET#, or when
addresses are stable for a specified period of time.
The
Write Protect (WP#)
feature protects the first or last sector by asserting a logic low on the WP#/ACC pin or WP# pin, depending
on model number. The protected sector is still protected even during accelerated programming.
The
Secure Silicon Region
provides a 128-word / 256-byte area for code or data that can be permanently protected. Once this
sector is protected, no further changes within the sector can occur.
Cypress MirrorBit flash technology combines years of flash memory manufacturing experience to produce the highest levels of
quality, reliability and cost effectiveness. The device electrically erases all bits within a sector simultaneously via hot-hole assisted
erase. The data is programmed using hot electron injection.
